Dust storms have proven deadly to motorists across the U.S. for years. Authorities say a dust storm last week reduced visibility to nearly zero on Interstate 70 in western Kansas.

A powerful storm system that tore across the United States in recent days is winding down Monday, but in its wake are devastated communities across states hit with violent tornadoes, wildfires and dust storms spun off by the massive system.

Meanwhile, the severe weather threat will linger through Sunday from Florida northward into the upper Ohio River Valley, forecasters warned.
